To all wlwm it may canoes u:

Be it known that I, RICHARD T. Hosnmo,

a citizen of the United States, residing at Saginaw, in the county of Saginaw and 2' State of Michigan, have invented certain new and useful improvements in Safety- Locks for Coin-Actuated Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the earns.

vThis invention relates to eoiaactuated machines and pertains more particularly to a safety incl; or guard adapted to be applied to eoin-actuated vending machines to prevent frat dulent delivery oi goods or stamps from the machine.

The invention relates more espechl y to 'coinaetnated stamp vending inaclnr of the type sliewn in my Pate t' No. ll 1539312, issued December 7, 19115, which comprises coiastaclting tube or receptacle in which eoinsare inserted by a manually operated feeding'in slide, the slide losing" suitably connected to a stamp delivery mechanism by which the stamp is deliver d from the machine after a coin been deposited the slide and during the return movement of the slide,

This device Q8311- a latch pivotally mounted upon a tionary member of the frame of the ma chine, titled with a stop and also carries a down- Wardly projecting central beveled tooth When a coin is on the slide and is beine, carried toward the reoeptaele, the advancing edge of the coin engages the beveled end tooth and lifts the latch the (rein and alide passing under the lower edge of the taste-i,

coin in the slide, it can loe pushed in to the end of its travel, with the result that Whentl e slide returns the stamp vending mechanism will be operated to deliver a stamp Without having deposited a coin.

Te prevent the latch from being'lifted and held in its raised position, either accidentally as by friction or binding of its pivot, or intentionally, as by a Wire inserted into the machine to lift the latch and hold it in its raised positioml providethe safety lost: or guard which forms one subject-matter of my present invention and which will new be described.

lit will be understood that for the purpose at? this present application any suitable stamp delivering device (not shown) may be actuated by the coin feeding-in 'slide, and that the mechanical connections between the f eding-in slide and the stamp delivering mechanism "will not operate to deliver a stamp unless the slide, carrying a coin of proper size, has been first pushed in to its tall ex. tent and then retracted by a spring or otherwise, ll prefer,l1owever, to use the an delivery mechanism shown and tie n the above-mentioned application,

.; niivalent thereof.

t invention consists in the devices de- "med and claimed and the equivalents nviagg's, .1 ure 1 is a top plan in Jillll, showing my iinapplit a coin-stacking stamp in: (712188 described. I as a part sectional elevation of the m shown in l, the seetionlaa of Fig. 1. a 3 a similar sectienai view with the latch and giiard in their raised positions, tl' sti eg tube being omitted.

and 5 are respectively top plan ind :lront view of the guard.

5 clearly shown in the drawings the onsists in a coin receptacle or tube iicli coins are fed ay the feeding oh s bask and forth along use 11; earned by the frame Milli}. v "rent the slid" Q from being pushed in tatenough to enable it to actuate the sis. in vendingmechanism on the return stroke, provided no coin has been deposited on the slide, I provide the stop 5. This step when down in the path of travel of the end of slide 2, as shown in Fig. l, and when raised allows the slide to pass. lly means of a beveled tooth 6 adapted to be engaged by thecoin, stop 5 is automatically raised clear of the slide when the slide is advanced with a coin in place, asshown in Fig. 53.

Both the stop 5 and the beveled tooth 6 are carried by a latch 7, wh'ch is preferably pivotally mounted to frame 4, as at 8. The latch is spring-pressed downwardly by a spring 9, also secured to frame 4t.

Beneath the point of the beveled tooth t which is carried by the pivoted latch 'l, l

locate a guard 10 which is in eli'ect a small plate, the upper surface of which bears yieldingly against the point of the tooth 6, being spring-pressed upwardly .so that the guard remains in contact with. and follows the tooth in its upward movement when the latch is raised.

Guard 10 is carried by an arm 11. which is pivotally mounted as at 12 on the frame 4 of the machine and is spring-pressed upwardly by means of the arm 13 and the spring 14, which is of less strength. than the spring 9 of latch 7.

Assuming that there is no coin. in the slide 2, if the latch 7 is raised, either accidentally or by intention, the guard plate 10 will follow the upward movement of the beveled tooth 6 and the ard will lie directly in the path of the a vancing slide 2, as shown in Fig. 3, so that the slide 2 will strike the guard and be prevented from further inward movement.

Assuming that a coin has been placed in the slide and that the latch 7 has been fraudulently raised, as by means of a wire inserted from outside the machine, .a flange 15 or equivalent projection on the guard 10 will engage the advancing edge or the coin and block the slide.

If the coin has been deposited in the slide,

' and the latch 7 is permitted to operate in its normal manncnthe coin and the slide will advance until the forward edge of the coin is above the edge of the guard 10, and the coin will then force its way in between the guard 10 and the point of the tooth 6, raising the latch 7 and the stop 5 and permitting the coin to pass into tube 1..

The slide 2, having thus been permitted to travel its full stroke, will actuate the stamp-vending mechanism on its return stroke, in the manner set forth in my pending application above referred to.

net-laser as has been heretofore noted, the operating connection between the slide 2 and the stamp vending mechanism is such in this type of machine that the vending mechanism will not operate to deliver a stamp unless the slide has first been pushed in to the extreme end of its travel.

Consequently the guard herein described effectually prevents fraudulent issue of stamps or goods from the vending machine.

Having thus described my invention, what I claim and desire to secure by Letters Patcut is:

1. A coin-controlled apparatus comprising a coin receptacle, a feeding-in slide adapted to deliver coins to said receptacle, a locking device comprising a yieldingly movable latch, a beveled tooth carried by said latch, a yieldingly movable guard normally bearing against the end of said tooth and adapted to yield to permit the passage of a coin between the tooth and guard when the latch is in normal position, and adapted to engage said slide to stop its forward movement when the latch is raised; a sto on said latch, normally located in-the patih of travel of said. slide and adapted to lift out of engagement with said slide when said tooth is lifted by a coin passing thereunder.

2. A coin-controlled apparatus comprising in combination, a coin receptacle, a feedingin slide, a yielding-1y movable latch, a stop and a beveled tooth carried [by said latch and adapted to engage respectively said slide and a coin carried by said slide, a guard member yieldingly pressed against the end of said tooth and adapted to be moved therewith into the path of travel of said slide, for the purposes set forth.

in testimon' v\whcreof, I affix my signature in presence of two witnesses.
